NAME
XcupGetReservedColormapEntries - list colormap entries reserved by the
system
SYNOPSIS
cc [ flag ... ] file ... -lXext [ library ... ]
#include <X11/extensions/Xcup.h>
Status XcupGetReservedColormapEntries(Display *display,
int screen, XColor **colors_out, int *ncolors);
ARGUMENTS
display Specifies the connection to the X server.
screen Screen number on the host server.
colors_out
Returns the values reserved by the server.
ncolors Returns the number of items in colors_out.
DESCRIPTION
The XcupGetReservedColormapEntries function returns a list of colormap
entries (pixels) that are reserved by the system. This list will, at a
minimum, contain entries for the BlackPixel and WhitePixel of the spec-
ified screen. Use XFree to free colors_out.
To minimize colormap flash, an application which installs its own pri-
vate colormap should query the special colors by calling XCupGetRe-
servedColormapEntries, and can then store those entries (in the proper
location) in its private colormap using XCupStoreColors.
